Here’s a few more:
The Mummy/The Mummy Returns (1999/2001)It’s been so long I can’t remember a, but I soooooo wanted to see Evelyn (Rachel Weisz) wind up in quicksand up to her neck somehow. I mean, c’mon, virtually the whole movie is set in a target rich environment (the desert!)
Lara Croft: Tomb Raider/The Cradle of Life (2001/2003)I’m sure Lara Croft has been mentioned time and time again on here so... need I go further? Again, it’s been forever since I’ve seen these so I can’t remember a specific part of the movie for a quicksand scene.
The Tall Men (1955)A movie I did see quite recently. There’s a part where it came so close to a quicksand scene that Ben (Clark Gable) even mentions it. The herd is crossing a river, and Nella (Jane Russell) rides up to Ben and noticing the cows swimming across she says: “There’s a shallower spot just up the river, why not cross them there?”, to which Ben replies: “why don’t you try it yourself!” This immediately got my attention and hopes up. A few minutes later, Ben points up the river and says to Nella’s boyfriend Nathan (Robert Ryan): “you better go help your responsibility!” Nathan looks, and Nella’s horse is stumbling in the shallow water about twenty feet from the edge and Nella falls off. She stumbles to shore, apparently in some mud (though not deep enough) before Nathan helps her the rest of the way. Walking by Ben, Nella says something about helping her get out of the mud to which he replies: “Mud? I thought it was quicksand!” and laughs. So close, but not quite a quicksand scene
